Dell G3 overheating issues (still under warranty)

So, I’ve been rocking this gaming laptop for just under a year now,

it’s running an i7 with 8GB of RAM and an Nvidia GTX 1660ti 8GB graphics card.

Lately, though, the thing just randomly shuts itself down right in the middle of a game. I’m pretty sure my GPU is overheating; I’ve been checking the Nvidia performance tools, and the temps are hitting 90°C, even though the card seems to pass standard benchmarks just fine.

I actually went ahead and ran a quick hardware diagnostic following the instructions from the Dell support desk—you know, hitting F9 during bootup—but wouldn't you know it? The laptop didn't detect any hardware issues or problems with the graphics card at all.

On top of that, I’ve cycled through every possible diagnostic available via the Dell self-service tool and updated my drivers multiple times. Yet, the issue persists—the laptop keeps cutting out while I'm gaming, which is incredibly frustrating.☕.

The thing is, my warranty expires in about a month, so I'm seriously considering filing a claim. What are my actual chances of getting this approved, and more importantly, how on earth am I supposed to prove to them that the machine is actually defective?

Just go ahead and drop it off for service, but maybe check if dust cleaning and thermal paste replacement are covered under warranty first. If they aren't, they'll probably charge you, and honestly, that's likely where the issue lies anyway.

The laptop isn't even a year old. Is it really possible for dust buildup or dried-out thermal paste to be the culprit this early?

Anyway, I swung by the dealer here in the States today where I originally bought the laptop to start the RMA process. They told me that if I leave it with them for the service/warranty claim, we're looking at a 4 to 6 week turnaround. Apparently, going through Dell directly might be a bit faster.

What a total disaster. What am I supposed to do now? I can't exactly go a month without my laptop...

I don't really know what to tell you, man. Maybe check if there's a repair shop nearby and see if they can squeeze you in quickly.

Dust could definitely be an issue after a year, though I guess it depends on how you've been using it...

Of course dust can be an issue, and in your case, that's likely the culprit. Generally speaking, cleaning out dust and reapplying thermal paste isn't covered under warranty, but even back home in the US, that wouldn't cost much, so it shouldn't be a big deal in America either.
But 4 to 6 weeks? I always assumed service centers were just slow in the states. What exactly are they planning to do? You mentioned the GPU is overheating. Most likely, the service center will tear the laptop down, blow out the dust, and then run some stress tests to see how the graphics card behaves. If the issue persists, they'll swap out the thermal paste. Then comes more testing, and if it still fails, they'll replace the graphics card entirely.

Knowing how service rates work—where you're paying for labor rather than actual parts—if a place in Austria is anything like one in Germany, all that "work" mentioned above is going to cost him an absolute fortune. And let’s be real, he clearly doesn't have that kind of cash lying around. If he did, he wouldn't be hanging out here hoping someone can fix an invisible Hardware issue for free in five minutes...

Here's the deal:


tldr; if you actually give a damn about Hardware and troubleshooting, just watch the video.
This guy is convinced his GPU is shot, so he sends just the card—not the whole PC—to a "repair center" because... well, he's just that sure. After they test it on an entirely different PC, run benchmarks, swap the thermal paste, and whatnot... turns out the graphics card is perfectly fine...

Pro tip:
If you have even a shred of technical curiosity, go to YouTube, type in your laptop model, and pair it with something like "How to clean out dust inside your laptop." I'm positive you'll find at least one video for your specific model—or at least something similar—showing you exactly how to open it up and clean it yourself.

If I open it up myself to try cleaning it, I lose my warranty. And what if it isn't just dust, but something else entirely? I'd honestly rather not mess around with it myself.

The reality is that I have a practically brand-new gaming laptop that isn't performing the way it should for its primary purpose. Honestly, I don't think it's my job to diagnose or fix the issue. That’s exactly why warranties exist, and why people who actually understand hardware should be the ones handling this.

My only real headache is being without a laptop for such a long stretch. If the turnaround was shorter—like a week or two max—I'd drop it off at the repair shop immediately. Instead, I'm sitting here overthinking my next move... that's really the only reason I made this post. I want to hear if anyone else has dealt with this or what you all think...

thanks everyone

If you’ve still got a warranty, take it back to them and make them fix it. Honestly, try asking for a loaner laptop while they deal with yours. Tell them you need it for work and that their incompetence isn't your burden to carry.

I know this might not mean much right now, but looking at other threads, I see you're a fan of Dell. Look, they aren't even a shadow of the company they used to be. If I were you, I’d steer clear of them from now on. The internet is flooded with complaints about their laptops—messy configurations plagued by massive thermal throttling, broken power management, and components that automatically downvolt just to prevent overheating. In the end, everything runs way slower than the specs actually suggest.

Also, check this out. Click the arrows next to the spoiler, especially that second image. I seriously couldn't fucking believe

"What if this, what if that..."—by the time you make up your mind, your warranty will be gone. You said yourself you've still got a month left; that month's gonna fly by, and then what?

You say it's not your job to troubleshoot, yet here you are, diving headfirst into diagnosing and guessing what's wrong instead of just heading straight to the service center or wherever you bought it to talk to the professionals whose actual job it is. You came to a forum to vent instead of dealing with it.

Look, if you actually needed this laptop for work—if your livelihood depended on it—you'd know exactly what to do right now. You wouldn't even be posting this here. You'd just file the claim, grit your teeth, deal with not gaming for a month, and move on.

And as for it being "practically new" after 11 months... well, we could go back and forth on that all day.

Well, of course I started troubleshooting... within reason and based on my own limited skill set. I'm not some lazy guy who's going to sprint to the repair shop the second a machine acts up without checking if there's something I can fix myself first...

The reality is that the issues kicked in once I started gaming through an external monitor with the laptop lid closed. That's when those random shutdowns during gaming sessions began. After doing some digging and thinking it through, I realized the setup was blocking the GPU from cooling properly through the keyboard area. I rearranged my gear so the laptop stays open while I'm gaming, and it seemed like the problem was solved.

I also installed a utility to monitor GPU temps and fan speeds because I had my doubts about whether they were even spinning correctly.

Then I reinstalled all the drivers.
Then I ran the built-in self-diagnostic tools...
etc.

Anyway, after all that work, it looks like the issue is still lingering, even if it's slightly less frequent now.

Well, if you get it now, just stop sitting there being quiet while you let that laptop overheat... maybe figure out a fix for it.

Also, it’s entirely possible that the second monitor has a higher resolution than the laptop screen itself. That would put even more strain on the GPU, especially since this laptop already struggles with thermal management. Normally, bumping up the resolution just eats into your VRAM, but modern games are packed with post-processing effects—think ambient occlusion, anti-aliasing, depth of field, or motion blur. When you're dealing with a more complex image, those functions demand more juice, which ends up taxing the Hardware even harder.

Is hitting 90 degrees Celsius on a high-end laptop GPU during intense gaming sessions actually something to worry about? I mean, I’m not entirely sure a machine would just shut itself down at 90; wouldn't it throttle the clock speeds first and only cut out once it clears 100? Could we be looking at an issue with the power delivery or maybe some kind of electrical hiccup?

Just buy an Apple Macbook Pro M1.
And honestly? They won't fix it anyway—it's a fundamental design flaw.

Even just transferring a basic image file can cause a laptop to heat up. I see this firsthand with my HUB. When I connect an Apple Macbook Pro M1 via a HUB to an HDMI port to view content on an external monitor, the HUB itself gets quite warm.

Called Dell today. The guy on the phone thinks it’s likely a motherboard issue. They said it should be sorted under warranty within 10 to 12 business days, which is a hell of a lot faster than what the folks at the retail store originally told me.

They did offer an expedited option where a technician comes straight to my place to fix it on-site for about $30—just covering the travel fee and stuff. Honestly, that sounds pretty reasonable; $30 isn't exactly breaking the bank compared to being stuck without my laptop for two whole weeks...

He should be heading over tomorrow.

By the way, the random shutdowns have been happening more frequently lately. This morning, after just 15 minutes of gaming while sipping my coffee, the thing just straight up booted into Safe Mode...

You’re gonna end up losing that $30 and being stuck without a laptop for two weeks—because there isn't a soul alive who's going to jump to fix some "potential" motherboard issue on the spot.

The whole thing was wrapped up in twenty minutes—basically just how long it took the guy to pop the casing and swap out the old motherboard for a new one.

GPU temps are way lower now, and honestly, the computer hasn't even flinched since Friday... 🎉
